Definitions

  • the invention relates to a ring nut with a foot part having a connection eyelet for hanging a stop or lashing means and with a threaded hole for its attachment to an object for a threaded pin.
  • Ring nuts of the above type are known from DIN 582. They are mass-produced articles which, unlike eyebolts in accordance with DIN 580, are used when there are no connection threaded holes on the objects to be transported, but only thread-free through holes are available.
  • the disadvantage of known ring nuts is that they do not automatically adjust to the pulling direction of lifting or lashing means without the risk of loosening or overtightening under load, as is the case with specially designed eye bolts according to EP 0 161 652 A2 and EP 0 654 611 Bl, the case is composed of at least two parts, one of which also forms a terminal lug and a threaded bolt, by which the connecting eye can execute rotary movements.
  • the invention has for its object to provide a ring nut of the type under consideration, the production of which is associated with only minimally increased effort compared to the production of ring nuts according to DIN 582 and whose connecting eye can adjust easily to the direction of the force introduced into it.
  • This object is achieved in that the threaded bore is formed by the bore of a rotatably and captively mounted sleeve in a recess of the foot part, one end of which projects slightly above the underside of the foot part of the connecting eye in the assembled state.
  • FIG. 2 shows the side view of the ring nut according to FIG. 1,
  • FIG. 3 partially in section a top view of the ring nut according to FIGS. 1 and 2, FIG. 4 on a reduced scale the fastening of the ring nut according to FIGS. 1 to 3 on a thicker plate,
  • FIG. 5 shows in section a slightly modified version of a ring nut
  • FIG. 6 shows the side view of the ring nut according to FIG. 5
  • FIG. 10 is a side view of the ring nut of FIG. 9,
  • FIG. 11 is a partial sectional top view of the ring nut of FIGS. 9 and 10,
  • FIGS. 9 to 11 shows a detail of the ring nut according to FIGS. 9 to 11 on an enlarged scale.
  • 1 is the foot part of a ring nut, into the connecting eye 2 of which an intermediate member 3, which enables the hooking of a crane hook (not shown), is welded.
  • a sleeve 5 is rotatably and captively mounted, which has a preferably continuous, circumferential support web 6, which is on a support surface 7 in the interior of the recess 4.
  • the support surface 7 and the mating surface of the support web 6 resting thereon are conical.
  • a spring ring 8 which is supported against a circumferential rib 9 at the upper end of the recess 4, serves to secure the position of the sleeve 5 in the recess 4.
  • the sleeve 5 has a threaded bore 10 into which a hexagon screw 11 is screwed in order to connect the ring nut to a plate 13 having a bore 12. So that the sleeve 5 does not rotate during the screwing process, it is provided with a head 14 designed as a hexagon, on which a screwing tool can engage.
  • the lower end of the sleeve 5 protrudes slightly above the underside 15 of the foot part 1 of the ring nut in the assembled state in order to ensure that the connecting eye 2 can rotate with respect to the sleeve 5.
  • FIG. 4 shows, on a reduced scale, an arrangement corresponding to FIG. 1, in which a ring nut is fastened to a thicker plate 17 with the aid of a longer screw 16.
  • Figure 4 consequently shows the more versatile uses of ring nuts compared to eye bolts.
  • the eyebolt shown in FIGS. 5 to 7 differs from the eyebolt according to FIGS. 1 to 4 only in that it has a modified foot part 18 of the connecting eye 2.
  • projections 19 on the upper edge of the recess 4 serve here.
  • a ring nut can be converted into an eyebolt using a threaded rod 20 provided with a transverse bore, in that the sleeve 5 is equipped with two transverse bores 22, 23 that can be used for receiving an adapter sleeve 21.
  • an adhesive connection can also be selected without the transverse bores 22, 23 naturally also makes it unnecessary to make a cross hole in the threaded rod.
  • the ring nut shown in FIGS. 9 to 12 corresponds to the ring nut according to FIGS. 1 to 3 with the proviso that instead of a spring ring 8 made of spring steel, a spring ring 23 made of an elastomer is used.
  • a spring ring 23 made of an elastomer is used.
  • Such an elastic spring ring 23 creates the prerequisites for preventing the screwing tool from slipping off the head 14 of the sleeve 5 when working overhead with the use of a screwing tool 25 connected to the connecting eye 2 with an annular collar 26 overlapping the head 14 of the sleeve 5.
  • the spring ring 24 fulfills a double function in that it secures the sleeve 5 on the one hand and the screwing tool 25 on the other hand in its or its position.

Abstract

L'invention concerne un écrou à anneau doté d'un élément pied (1) et d'un oeillet de raccordement (2) pour moyens de butée et d'amarrage. Afin de garantir sur cet écrou que la position de l'oeillet de raccordement (2) soit réglée en fonction de la force qui est appliquée à ce dernier, une gaine (5) dotée d'un taraudage (10) est logée dans un creux (4) de l'élément pied (1) de l'écrou à anneau, l'extrémité de cette gaine dépassant légèrement au-dessus de la partie inférieure de l'élément pied (1) rotatif, en face de la gaine (5).
